2022-10-11wifi: ath11k: mac: fix reading 16 bytes from a region of size 0 warningKalle Valo
Linaro reported stringop-overread warnings in ath11k (this is one of many): drivers/net/wireless/ath/ath11k/mac.c:2238:29: error: 'ath11k_peer_assoc_h_he_limit' reading 16 bytes from a region of size 0 [-Werror=stringop-overread] My further investigation showed that these warnings happen on GCC 11.3 but not with GCC 12.2, and with only the kernel config Linaro provided: https://builds.tuxbuild.com/2F4W7nZHNx3T88RB0gaCZ9hBX6c/config I saw the same warnings both with arm64 and x86_64 builds and KASAN seems to be the reason triggering these warnings with GCC 11. Nobody else has reported this so this seems to be quite rare corner case. I don't know what specific commit started emitting this warning so I can't provide a Fixes tag. The function hasn't been touched for a year. I decided to workaround this by converting the pointer to a new array in stack, and then copying the data to the new array. It's only 16 bytes anyway and this is executed during association, so not in a hotpath.

Checking the relevant rxd bits for the checksum information only indicates if the checksum verification was performed by the hardware and doesn't show actual checksum errors. Checksum errors are indicated in the info field of the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY by checking the extra bits as well. Those bits are only passed to the driver for MMIO devices at the moment, so limit checksum offload to those.

2022-10-11wifi: mt76: fix receiving LLC packets on mt7615/mt7915Felix Fietkau
When 802.3 decap offload is enabled, the hardware indicates header translation failure, whenever either the LLC-SNAP header was not found, or a VLAN header with an unregcognized tag is present. In that case, the hardware inserts a 2-byte length fields after the MAC addresses. For VLAN packets, this tag needs to be removed. However, for 802.3 LLC packets, the length bytes should be preserved, since there is no separate ethertype field in the data. This fixes an issue where the length field was omitted for LLC frames, causing them to be malformed after hardware decap.

2022-10-11can: kvaser_usb_leaf: Fix TX queue out of sync after restartAnssi Hannula
The TX queue seems to be implicitly flushed by the hardware during bus-off or bus-off recovery, but the driver does not reset the TX bookkeeping. Despite not resetting TX bookkeeping the driver still re-enables TX queue unconditionally, leading to "cannot find free context" / NETDEV_TX_BUSY errors if the TX queue was full at bus-off time. Fix that by resetting TX bookkeeping on CAN restart. Tested with 0bfd:0124 Kvaser Mini PCI Express 2xHS FW 4.18.778.

2022-10-11can: kvaser_usb: Fix use of uninitialized completionAnssi Hannula
flush_comp is initialized when CMD_FLUSH_QUEUE is sent to the device and completed when the device sends CMD_FLUSH_QUEUE_RESP. This causes completion of uninitialized completion if the device sends CMD_FLUSH_QUEUE_RESP before CMD_FLUSH_QUEUE is ever sent (e.g. as a response to a flush by a previously bound driver, or a misbehaving device). Fix that by initializing flush_comp in kvaser_usb_init_one() like the other completions. This issue is only triggerable after RX URBs have been set up, i.e. the interface has been opened at least once.

2022-10-11can: kvaser_usb_leaf: Fix overread with an invalid commandAnssi Hannula
For command events read from the device, kvaser_usb_leaf_read_bulk_callback() verifies that cmd->len does not exceed the size of the received data, but the actual kvaser_cmd handlers will happily read any kvaser_cmd fields without checking for cmd->len. This can cause an overread if the last cmd in the buffer is shorter than expected for the command type (with cmd->len showing the actual short size). Maximum overread seems to be 22 bytes (CMD_LEAF_LOG_MESSAGE), some of which are delivered to userspace as-is. Fix that by verifying the length of command before handling it. This issue can only occur after RX URBs have been set up, i.e. the interface has been opened at least once.

2022-10-09mISDN: hfcpci: Fix use-after-free bug in hfcpci_softirqDuoming Zhou
The function hfcpci_softirq() is a timer handler. If it is running, the timer_pending() will return 0 and the del_timer_sync() in HFC_cleanup() will not be executed. As a result, the use-after-free bug will happen. The process is shown below: (cleanup routine) | (timer handler) HFC_cleanup() | hfcpci_softirq() if (timer_pending(&hfc_tl)) | del_timer_sync() | ... | ... pci_unregister_driver(hc) | driver_unregister | driver_for_each_device bus_remove_driver | _hfcpci_softirq driver_detach | ... put_device(dev) //[1]FREE | | dev_get_drvdata(dev) //[2]USE The device is deallocated is position [1] and used in position [2]. Fix by removing the "timer_pending" check in HFC_cleanup(), which makes sure that the hfcpci_softirq() have finished before the resource is deallocated.

This significantly improves TCP segment coalescing and simplifies deployments as different workloads benefit from HW or SW GRO. - Shrink the size of the base zero-copy send structure. - Move TCP init under a new slow / sleepable version of DO_ONCE(). BPF: - Add BPF-specific, any-context-safe memory allocator. - Add helpers/kfuncs for PKCS#7 signature verification from BPF programs. - Define a new map type and related helpers for user space -> kernel communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF). - Allow targeting BPF iterators to loop through resources of one task/thread. - Add ability to call selected destructive functions. Expose crash_kexec() to allow BPF to trigger a kernel dump. Use CAP_SYS_BOOT check on the loading process to judge permissions. - Enable BPF to collect custom hierarchical cgroup stats efficiently by integrating with the rstat framework. - Support struct arguments for trampoline based programs. Only structs with size <= 16B and x86 are supported. - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping sockets (instead of just TCP and UDP sockets). - Add a helper for accessing CLOCK_TAI for time sensitive network related programs. - Support accessing network tunnel metadata's flags. - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open. - Add support for writing to Netfilter's nf_conn:mark. Protocols: - WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation (MLO) work (802.11be, WiFi 7). - vsock: improve support for SO_RCVLOWAT. - SMC: support SO_REUSEPORT. - Netlink: define and document how to use netlink in a "modern" way. Support reporting missing attributes via extended ACK. - IPSec: support collect metadata mode for xfrm interfaces. - TCPv6: send consistent autoflowlabel in SYN_RECV state and RST packets. - TCP: introduce optional per-netns connection hash table to allow better isolation between namespaces (opt-in, at the cost of memory and cache pressure). - MPTCP: support TCP_FASTOPEN_CONNECT. - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior. - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets. - Open vSwitch: - Allow specifying ifindex of new interfaces. - Allow conntrack and metering in non-initial user namespace. - TLS: support the Korean ARIA-GCM crypto algorithm. - Remove DECnet support. Driver API: - Allow selecting the conduit interface used by each port in DSA switches, at runtime. - Ethernet Power Sourcing Equipment and Power Device support. - Add tc-taprio support for queueMaxSDU parameter, i.e. setting per traffic class max frame size for time-based packet schedules. - Support PHY rate matching - adapting between differing host-side and link-side speeds. - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode. - Validate OF (device tree) nodes for DSA shared ports; make phylink-related properties mandatory on DSA and CPU ports. Enforcing more uniformity should allow transitioning to phylink. - Require that flash component name used during update matches one of the components for which version is reported by info_get(). - Remove "weight" argument from driver-facing NAPI API as much as possible.

Add interface to support Power Sourcing Equipment. At current step it provides generic way to address all variants of PSE devices as defined in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4 PoDL Power Sourcing Equipment (PSE). Currently supported and mandatory objects are: IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl This is minimal interface needed to control PSE on each separate ethernet port but it provides not all mandatory objects specified in IEEE 802.3-2018. Since "PoDL PSE" and "PSE" have similar names, but some different values I decide to not merge them and keep separate naming schema. This should allow as to be as close to IEEE 802.3 spec as possible and avoid name conflicts in the future. This implementation is connected to PHYs instead of MACs because PSE auto classification can potentially interfere with PHY auto negotiation. So, may be some extra PHY related initialization will be needed.

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull kernel hardening updates from Kees Cook: "Most of the collected changes here are fixes across the tree for various hardening features (details noted below). The most notable new feature here is the addition of the memcpy() overflow warning (under CONFIG_FORTIFY_SOURCE), which is the next step on the path to killing the common class of "trivially detectable" buffer overflow conditions (i.e. on arrays with sizes known at compile time) that have resulted in many exploitable vulnerabilities over the years (e.g. BleedingTooth). This feature is expected to still have some undiscovered false positives. It's been in -next for a full development cycle and all the reported false positives have been fixed in their respective trees. All the known-bad code patterns we could find with Coccinelle are also either fixed in their respective trees or in flight. The commit message in commit 54d9469bc515 ("fortify: Add run-time WARN for cross-field memcpy()") for the feature has extensive details, but I'll repeat here that this is a warning _only_, and is not intended to actually block overflows (yet). The many patches fixing array sizes and struct members have been landing for several years now, and we're finally able to turn this on to find any remaining stragglers. Summary: Various fixes across several hardening areas: - loadpin: Fix verity target enforcement (Matthias Kaehlcke). - zero-call-used-regs: Add missing clobbers in paravirt (Bill Wendling). - CFI: clean up sparc function pointer type mismatches (Bart Van Assche). - Clang: Adjust compiler flag detection for various Clang changes (Sami Tolvanen, Kees Cook). - fortify: Fix warnings in arch-specific code in sh, ARM, and xen. Improvements to existing features: - testing: improve overflow KUnit test, introduce fortify KUnit test, add more coverage to LKDTM tests (Bart Van Assche, Kees Cook). - overflow: Relax overflow type checking for wider utility. New features: - string: Introduce strtomem() and strtomem_pad() to fill a gap in strncpy() replacement needs. - um: Enable FORTIFY_SOURCE support. - fortify: Enable run-time struct member memcpy() overflow warning" * tag 'hardening-v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (27 commits) Makefile.extrawarn: Move -Wcast-function-type-strict to W=1 hardening: Remove Clang's enable flag for -ftrivial-auto-var-init=zero sparc: Unbreak the build x86/paravirt: add extra clobbers with ZERO_CALL_USED_REGS enabled x86/paravirt: clean up typos and grammaros fortify: Convert to struct vs member helpers fortify: Explicitly check bounds are compile-time constants x86/entry: Work around Clang __bdos() bug ARM: decompressor: Include .data.rel.ro.local fortify: Adjust KUnit test for modular build sh: machvec: Use char[] for section boundaries kunit/memcpy: Avoid pathological compile-time string size lib: Improve the is_signed_type() kunit test LoadPin: Require file with verity root digests to have a header dm: verity-loadpin: Only trust verity targets with enforcement LoadPin: Fix Kconfig doc about format of file with verity digests um: Enable FORTIFY_SOURCE lkdtm: Update tests for memcpy() run-time warnings fortify: Add run-time WARN for cross-field memcpy() fortify: Use SIZE_MAX instead of (size_t)-1 ...
2022-10-03net: marvell: prestera: Propagate nh state from hw to kernelYevhen Orlov
We poll nexthops in HW and call for each active nexthop appropriate neighbour. Also we provide implicity neighbour resolving. For example, user have added nexthop route: # ip route add 5.5.5.5 via 1.1.1.2 But neighbour 1.1.1.2 doesn't exist. In this case we will try to call neigh_event_send, even if there is no traffic. This is useful, when you have add route, which will be used after some time but with a lot of traffic (burst). So, we has prepared, offloaded route in advance.

2022-10-03net: marvell: prestera: Add neighbour cache accountingYevhen Orlov
Move forward and use new PRESTERA_FIB_TYPE_UC_NH to provide basic nexthop routes support. Provide deinitialization sequence for all created router objects. Limitations: - Only "local" and "main" tables supported - Only generic interfaces supported for router (no bridges or vlans) Co-developed-by: Taras Chornyi <tchornyi@marvell.com> Signed-off-by: Taras Chornyi <tchornyi@marvell.com> Co-developed-by: Oleksandr Mazur <oleksandr.mazur@plvision.eu> Signed-off-by: Oleksandr Mazur <oleksandr.mazur@plvision.eu> Signed-off-by: Yevhen Orlov <yevhen.orlov@plvision.eu> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
